Theresa
★★★★★

“I asked my Optometrist her opinion of Clearer. She immediately looked up the product. The ingredients are correct and there are no fillers. Now more than 6 months later after an eye scan, she was able to compare my eyes to previous visit and said there was definite improvement.”

Rachel
★★★★★

“I have been taking Clearer for a few months now and I have noticed a huge difference in my vision and eye floaters.”

David
★★★★★

“I have been on it 2 months, went for annual eye test yesterday and was told good enough to be a pilot! Not bad at 77 years old.”

Andrew
★★★★★

“I was very skeptical about trying these - I have floaters and squiggly filaments which have been getting worse over the past couple of years. I have been using the capsules for nearly two months and I can definitely notice a difference.”

Sam
★★★★★

“I have been on it for four months and have already noticed fading of my floaters. I will stay on it as long as you keep making it.”

What’s inside

Grape seed extract (52.6 mg, 120:1), bitter orange (200 mg), L-lysine (250 mg), vitamin C (80 mg), zinc citrate (10 mg) and marigold flower powder giving about 10 mg lutein and 0.83 mg zeaxanthin per capsule.

Other ingredients: slow-release HPMC capsule shell and organic brown rice flour.

How to use

One capsule a day, with or after a meal.

The floater study behind Clearer® ran for six months of daily use, which is why we suggest a six-month routine. Oxidative stress and glycation add up over the years, so daily support matters for the long term.

The research

Clearer® is formulated with reference to a six-month, randomised, double-blind, placebo-controlled trial published in 2021. It has the five studied nutrients at twice the amounts listed in the study, plus lutein and zeaxanthin, with 100% of the daily reference for vitamin C and zinc, and zinc as citrate, a well-absorbed form.

Pre-order and shipping

Clearer® is on pre-order. The next batch arrives by 7 November, and pre-orders are dispatched first, in the order they were placed. Payment is taken when you order. If you change your mind before dispatch, email info@clearereyes.com for a full refund.

Free UK shipping. Tracked international shipping to 40+ countries. If your order includes other products, everything ships together with your pre-order.

Sudden new floaters, flashes of light or a shadow across your vision need urgent eye care. Food supplements are not a substitute for a varied diet.

The research

Eye floater support

Clearer® is formulated with reference to a six-month, double-blind, placebo-controlled trial. The measured area of vitreous opacities, the clumps behind floaters, decreased on imaging in 77% of people on the formula, compared with 29% on placebo.

Clearer® has the same five nutrients at twice the amounts listed in the study: L-lysine, vitamin C, grape seed extract, zinc and bitter orange. Six months of daily use is what the study measured.

Illustration: the back of the eye, reconstructed from a real retinal photograph, with the macula at the centre and the optic disc on the right.
The research

Macular health

Your macula is the small centre of the retina behind your sharpest vision. Lutein and zeaxanthin concentrate there as its yellow pigment, absorb blue light and act as antioxidants.

In a one-year trial, 10 mg of lutein a day with zeaxanthin raised macular pigment compared with placebo. Each Clearer® capsule gives you about 10 mg of lutein.

Lutein & zeaxanthin one-year trial (2014)National Eye Institute: AREDS & AREDS2
The mechanism

Collagen integrity

A fine network of collagen keeps your vitreous clear, and your eye makes little, if any, new collagen after infancy. Oxidative stress and glycation, where sugars bond to proteins, are linked with collagen ageing, and clumped fibres cast the shadows you see.

Clearer® combines grape seed, citrus flavonoids and lysine, studied in the lab against glycation, with vitamin C, which your skin’s collagen-making cells depend on.

The research

Antioxidant protection

Oxidative stress is damage from reactive oxygen molecules. Your eye is especially exposed: it takes in light constantly and uses a lot of oxygen, and its natural defences decline with age.

In a lab comparison, grape seed extract neutralised 78–81% of two free radicals, vitamin C 12–19%. Vitamin C and zinc help protect your cells from oxidative stress, and zinc helps maintain normal vision.

Collagen integrity

Sugars stiffen collagen that keeps eyes clear. Lysine curbed it in tests.

Macular health

10 mg lutein, as in major eye trials, for the macula behind sharp vision.

Antioxidants

Your eye's gel hoards vitamin C, its key antioxidant. You get 80 mg.

Why Clearer® is unlike other eye supplements

Few eye supplements give you all of this in one capsule: nutrients from a floater trial, support for your macula, a clean formula and forms your body absorbs well.

Dark dots and squiggly lines that spoil a beautiful blue sky

They drift across the page and dart away when you look. For a long time, they were written off as a normal part of ageing, something to live with.

Behind them is vitreous degeneration: the gel inside your eye breaks down with age, whether you notice floaters or not.

This page is about age-related floaters. Sudden floaters, flashes or a curtain across your vision can signal an urgent eye problem: get same-day assessment.

A bright blue sky with soft clouds, and the dark threads and dots of floaters drifting across it

Eye floaters are not just normal. They are collagen damage.

The collagen in your eye’s clear gel is prone to damage over time. Damaged fibres clump together, and you see their shadows as floaters.

Cross-section of an eye: a beam of light passes through the cornea and lens, meets a collagen clump in the clear gel and casts a shadow on the retina

Light enters the eye

Light passes through the cornea and lens, then through the clear gel towards your retina.

A collagen clump crosses the path

Inside the gel, strands of collagen clump together and sit in the path of the light.

A shadow is cast on the retina

The clump casts a soft, moving shadow on your retina. That shadow is the floater you see.

Clear vision relies on collagen that has to last a lifetime

A fine network of collagen keeps your vitreous clear, and your eye makes little, if any, new collagen after infancy. So damage adds up over the years.

Collagen breakdown

With age, the collagen breaks down. Fibres clump, and water separates out of the gel into pockets of liquid called lacunae.

Oxidative stress
Light and oxygen create free radicals that can break down hyaluronan and damage collagen.
Glycation
Sugars slowly bond to collagen in everyone, cross-linking its fibres.

Targeted support

Clearer® gives you daily antioxidants and anti-glycation nutrients, aimed at two of the processes that damage vitreous collagen.

Vitreous liquefaction

The breakdown accelerates after 40. As the collagen fibres clump together, they leave spaces where the gel turns liquid. Everybody’s vitreous degenerates with age, whether or not they notice floaters yet.

In a six-month trial, nutrients eased the discomfort of floaters

You may have been told to live with floaters. Researchers tested five targeted nutrients against placebo, then measured opacities, the clumps behind floaters, on imaging.

On placebo

Educational information. Clearer HealthTech is not affiliated with the research institution, and Clearer® itself was not the product tested. It was formulated with reference to the research by expert nutritionists, and contains not only those five nutrients at double the listed amounts, with zinc as citrate, but also macular support for the whole eye.

Does it mean that floaters were eliminated?
No, and no honest supplement can promise that. What changed was the measured area of the clumps on imaging and how much they bothered people, and more people improved on both measures on the formula than on placebo.
Do floaters disappear by themselves anyway?
Many people notice them less over time. That fading is neuroadaptation: your brain learns to ignore the shadow while the clump stays. A camera does not adapt, so the imaging result above is not just your brain tuning out. Discomfort, out of 6, fell from 3.90 to 2.10 on the formula and barely changed on placebo (3.69 to 3.35).
How do nutrients reach the vitreous?
Through your blood. Your eye actively pumps vitamin C into its gel, where levels are about 12 times those in your blood. In guinea pigs, which like us must get vitamin C from food, levels in the eye rose with intake and then levelled off. In people, oral vitamin C raises levels at the front of the eye; levels in the vitreous have not yet been measured after a dose. As for grape seed, related plant compounds taken by mouth have been measured in eye tissue in animals, and one reached the human vitreous in a small surgical study.
Why these nutrients?
Researchers chose them to counter oxidation and sugar damage, two processes linked with an ageing vitreous.
  • Vitamin C: your eye concentrates it in the gel, where it works as an antioxidant.
  • Grape seed: its polyphenols are strong antioxidants and help block sugar damage in lab tests, and it has been studied for the retina too.
  • Bitter orange: carries citrus flavonoids, such as hesperidin, studied in the lab for limiting sugar damage to long-lived proteins, including in your lens.
  • L-lysine: naturally present in your vitreous, and the best of three agents at blocking sugar damage to vitreous collagen in a lab study.
  • Zinc: your eye is one of the body’s richest stores of zinc, and zinc helps your cells defend against oxidative stress.

Clearer® adds lutein and zeaxanthin, which form the yellow pigment of your macula, the part of your retina behind your sharpest central vision.

If the vitreous is so important, why didn’t my optician tell me?
Floaters are so common they have long been seen as a normal part of ageing. Your optician’s first job is to check your retina is safe, and the usual advice is reassurance. The research is also young: the placebo-controlled nutrient trial on floaters was only published in 2021, and vitreous research is small beside the retina’s. And medicine grew up treating disease. Studying ageing itself, and acting before problems start, is a newer idea from longevity science. That is the thinking behind looking after your eyes early.
Aren’t eye floaters normal?
Age-related floaters are normal in the sense that wrinkles are normal: very common, and a sign of ageing. Like wrinkles, they tell you something is changing underneath, and that is worth looking after.

Clearer® is an excellent new product to the market. I am pleased to see that the combination of ingredients is research driven and in therapeutic dosages.

The incidences of poor eye health are increasing dramatically. The cause of this is multifactorial but the surge in screen time is undoubtably a large contributor to this problem.

Clearer® contains the ingredients of lutein and zeaxanthin. These are powerful antioxidants which not only help protect the eyes from sun damage but help to filter out harmful blue light. Research has shown that this dosage produced improvements in mean eye macular pigment optical density, visual acuity and contrast sensitivity. Both lutein and zeaxanthin are present in the lens and retina of the eye.

Of equal importance is the forms of the nutrients in this product. For example, zinc is in the form of zinc citrate. This means that it is absorbed by the body in a greater amount than some poorly absorbed forms.

Vitamin C which is in the product also helps protect against UV light damage. We know that the concentration of Vitamin C in the eyes lessens with age. It is therefore important to have enough Vitamin C to counteract this. Vitamin C is an antioxidant and oxidative damage is a key factor in two common age-related cataracts – cortical and nuclear cataracts.

It is good to see the additional ingredients of lysine, citrus aurantium and grape seed extract in Clearer®. Lysine is an essential amino acid that our body cannot manufacture. We therefore need to obtain it from supplementation or dietary sources. Studies have shown that lysine supplements could prevent the development of cataract.

Citrus Aurantium is often known as Bitter Orange. It has been shown to improve the visual function of users suffering from vitreous degeneration or “floaters” within the eye when taken alongside the other nutrients found in this product. Grapeseed Extract is a powerful antioxidant. Antioxidants help guard against oxidative damage to the eye. They are sometimes called free-radical scavengers as they can prevent or slow down the damage caused by free radicals. Free radicals are unstable molecules that the body produces as a result of a reaction to environmental pressures. Oxidative stress is an imbalance between free radicals and antioxidants in the body. This can result in the free radicals doing damage to fatty tissue, DNA and proteins in the body. Antioxidants are beneficial as they cause the free radicals to stabilize and become less reactive. We can therefore see how oxidative damage can be harmful and how antioxidants can be helpful in reducing this risk.

Of particular interest are the products' ingredients to help tackle eye floaters. The product was formulated according to peer-reviewed research regarding eye floaters. Research was conducted on lysine, Vitamin C, zinc and citrus aurantium. The results showed that patients reported a significant decrease in their visual discomfort from floaters compared to the placebo group who had no significant change in their visual discomfort. Clearer® was formulated to ensure a good intake of nutrients required to help with eye floaters.

Overall, this is an innovative supplement to address the growing concern of eye health including both vitreous and macular health and protecting the eyes from oxidative damage, blue light, and UV. I haven’t seen a supplement in the UK which has this unique blend of nutrients. It is an important supplement for anyone who is spending many hours in front of a digital screen and wants good eye protection.

Your eye actively concentrates it in its clear gel, at about 12 times the level in your blood.

Zinc citrate

10 mg

MineralAntioxidant defence

Helps your cells defend against oxidative stress, and comes in a form your body absorbs well.

Lutein + zeaxanthin

10 mg lutein

CarotenoidMacular pigment

They form the yellow pigment of your macula, behind your sharpest central vision.

Grape seed extract

52.6 mg of extract (120:1), equivalent to 6,312 mg of grape seeds.

How it helps your eyes

Its polyphenols, including proanthocyanidins, act as antioxidants and help block glycation in the lab. One of the five nutrients in the floater study.

The research

Lab test: at the same amount, grape seed extract neutralised 78–81% of two free radicals. Vitamin C neutralised 12–19%.

Bagchi, Res Commun Mol Pathol Pharmacol, 1997

Lab test: muscadine grape seed extract cut glycation products by about 65%.

Farrar, BioFactors, 2007

Human and animal studies: grape seed has also been studied for the retina, including in a year-long human trial.

Moon, Medicine, 2019; Li, Arch Pharm Res, 2020

For your whole body

Studied in human trials for markers of oxidative stress, and in small human trials for skin.

Bitter orange

200 mg of bitter orange (Citrus aurantium) powder.

How it helps your eyes

Carries citrus flavonoids, such as hesperidin, studied in the lab for limiting sugar damage to long-lived proteins, including in your lens. One of the five nutrients in the floater study.

The research

Lab test: hesperidin and its relatives blocked glycation. The best form, hesperetin, reached 57% and 38% in two assays.

Li, Pharm Biol, 2012

Lab and animal study: in human lens cells and mouse lens cultures, hesperetin reduced glycation of lens proteins.

Doki, Mol Med Rep, 2023

For your whole body

In an animal study at a high dose, oral hesperidin reduced wrinkles and collagen fibre loss in UV-exposed mice.

L-lysine

250 mg of L-lysine monohydrochloride.

How it helps your eyes

An essential amino acid your body can’t make. In your eye it is studied against sugar damage to collagen. One of the five nutrients in the floater study.

The research

Lab study on human vitreous collagen: lysine was the best of three agents, cutting glucose uptake by 76%.

Sulochana, Med Sci Monit, 2003

Review of skin collagen: enzymes that depend on vitamin C modify lysine so fibres can form stable links.

The science behind a six-month routine

Explore a different part of the science each month, from daily nutrition to the six-month floater trial.

Month 1

Working from your very first capsule

Take one with a meal and the nutrients start absorbing into your system straight away. Vitamin C is taken up almost completely, and grape seed compounds circulate within hours.

Month 2

Antioxidants for your whole body

Grape seed proanthocyanidins travel through your whole body. In studies of elite athletes, grape extracts raised antioxidant capacity, even under the stress of hard training.

Month 3

A stronger light filter for sharp vision

10 mg of lutein a day, the amount in Clearer®, raises macular pigment in studies: the yellow filter at the centre of your sharpest vision.

Month 4

Protection that builds month on month

Lutein levels rise within two weeks, and the pigment keeps building over the months that follow. Every daily capsule adds to it.

Month 6

Give it the time the study gave

The floater study ran for six months, one capsule a day. Clearer® has the same five nutrients at twice the listed amounts, plus lutein for your macula.

Month 6+

Antioxidant care that lasts for years

Your eyes are metabolically active and prone to oxidative stress. Their antioxidant defences fall with age, and daily vitamin C and zinc help protect your cells from that stress.

Good for your eyes, great for your body

Your eyes aren’t separate from the rest of you. What you take for them travels in your blood to your skin, your blood vessels and your brain.

For your skin

In skin, as in your eye’s gel, collagen lasts for years and sugar slowly cross-links it. These nutrients work from the inside.

An older woman with silver hair, in soft daylight
Illustration: a cross-section of skin, with vitamin C from a small blood vessel reaching a collagen-making cell in the deep layerIllustration: a cross-section of skin, with yellow-orange carotenoids in the upper layersIllustration: a cross-section of skin, with antioxidants in its living layer

Your collagen-making cells depend on vitamin C, which reaches them through your blood. Zinc helps maintain normal skin, hair and nails.

Vitamin C helps the enzymes that stabilise each collagen molecule, and it promotes the genes that make collagen. Skin collagen renews so slowly that half of it is still there after about 15 years, so sugar damage builds: about five times as much by age 85 as at age 20.

Lutein and zeaxanthin build up in your skin. In a 12-week trial at 10 mg lutein, overall skin tone improved compared with placebo.

In one small study at a higher dose, skin levels were up by week 4. The 12-week trial was double-blind and placebo-controlled: people on lutein rated their overall skin tone better than those on placebo, and a colour meter recorded a change in their skin colour.

Every day, light and oxygen put your skin under oxidative stress. Vitamin C and zinc help protect its living cells.

Many parts of your skin’s antioxidant defence, including vitamin C, come from your diet. Clearer® gives you 100% of the daily reference for vitamin C and zinc, which also support your immune system. Grape seed extract has been studied in human trials for markers of oxidative stress.

For your heart and circulation

Vitamin C helps form the collagen your blood vessels depend on. In human trials at higher doses, grape seed extract has been studied for blood pressure.

For your brain

Zinc helps maintain normal cognitive function. In one trial of 10 mg lutein with zeaxanthin, visual memory and learning improved more than on placebo.

What people ask before they order

Does Clearer® actually work?
Its five core nutrients have placebo-controlled evidence behind them. In a 2021 trial, measured opacity area decreased in 20 of 26 people (77%) on the studied formula, compared with 6 of 21 (29%) on placebo. At six months, 11 of 30 (37%) on the formula said their condition was stable and their floaters did not bother them, compared with 4 of 26 (15%) on placebo. Clearer® has each nutrient at twice the amount listed in the study, plus 10 mg of lutein.
Isn't the study sample size small?
Yes: 61 people over six months, in a randomised, double-blind, placebo-controlled trial that measured floaters on eye imaging as well as by questionnaire. Nutrition trials are expensive and rarely get drug-trial budgets, so many are this size. The trial is also not the only research behind the formula: your eye concentrates vitamin C in the gel where floaters form, and 10 mg of lutein is the amount used in major eye-nutrition trials. More than 10,000 people have chosen Clearer® since 2023.
Is Clearer® a treatment for eye floaters?
No. Clearer® is a food supplement. It is not intended to diagnose, treat, cure, remove or prevent eye floaters or any disease. Persistent, new or changing symptoms require eye exams and should be discussed with an optometrist or ophthalmologist.
Will it work on my floaters?
Most floaters come with age or short sight, and those are the people the study enrolled, including many whose gel had already come away from the retina. Clearer® also supports your macula and overall eye health, so it does more than target floaters.
I already take eye vitamins with lutein. Isn’t that the same?
Not quite. Lutein and zeaxanthin concentrate in your macula, at the back of your eye. Floaters come from the vitreous, the clear gel in front of it, and that is where the floater research looked. Clearer® gives you both.
What if I have sudden new floaters, flashes or a curtain in my vision?
Do not wait to see whether a supplement helps. Sudden floaters, flashes, a curtain or shadow, eye pain or reduced vision can require prompt eye assessment. Seek urgent professional advice.
How long until I notice a difference?
The floater study measured results at six months of daily use, so that is the fairest point to judge. Some customers describe gradual change after a few months, and it helps to note your floaters in month one so you can compare. Many customers keep going after six months, because the collagen in your eye has to last a lifetime, and sugar and oxygen keep working on it every day. Our 180-day money-back guarantee, from delivery, takes the risk out of finding out.
Is it vegan?
Yes, 100% vegan, including the slow-release capsule shell. No chemical fillers, no artificial excipients, and the bottle is plant-based, made from sugar cane.
I struggle with swallowing capsules. What can I do?
You can open a capsule and mix the powder into food or a drink, ideally with a meal. You lose the slow-release shell that way, but you still get all the nutrients. Many of our customers do that.
Do you ship to my country?
Yes. UK shipping is free, and we offer tracked international shipping to 40+ countries, including the US, where thousands of customers take Clearer®.

Sudden floaters, flashes, a curtain or veil, eye pain, trauma or reduced vision can indicate an urgent retinal or eye problem. Seek same-day professional assessment. Clearer® is a food supplement and does not diagnose, treat, cure or prevent disease.
